SPECIFICATION forming'part of Letters Patent No. 510,732, dated December12, 189.3.

Application filed February 8, 1893. Serial No. 461,442. (1N/o model.)Patented in France April 21, 1892, No. 221,070 in Belgium April 28,1892, No.A 99,462; in England May 5, 1892, No. 8,559; in Spain .Tu-11e15, 1892, No. 18,354; in Italy .Tune 30, 1892, No. 81,847; in PortugalSeptember 15,1892, No. 1,710, and in Turkey October 26, 1892, No. S01.

1892, No. 301,) of which the following is a specification.

My invention relates to strainers for oil and similar presses. l

In the accompanying drawings, Figure 1 is a vertical section showing thegeneral ar rangement of a strainer, the sides of which are constructedaccording to my invention. Fig. 2 is a horizontal section of the sametaken on the line 1-2 of Fig. 1. Fig. 3 is a transverse section of themetallic strips constituting the sides of the strainer drawn to anenlarged scale. Fig. 4 is a longitudinal section of one of 'thesemetallic strips also drawn to an enlarged scale.

The metallic strips f f are of such a section that when their rear partsare placed to:V

gether narrow slits t' z' will be left in front which do not vary'insize during the work of compression.. These slits terminate inlongitudinal channels jj which are open at their' lower ends. Each groupof slits constituting one of the sides of the strainer is xed to asegment s by means of a key or' wedge which insures contact between allthe strips. The said strips are interchangeable, and have dovetailextremities and are held against the segments s of the strainer by meansof a plate k iixed by screws. The segments are inclosed in a casing T ofsheet iron or other suitable material and the spaces formed'between thecasing T and the segments permits of the circulation of steam tofacilitate the running off of the oil. Under the force produced by ahydraulic press the oil or other liquid expelled from the solidmaterials Will pass through the slits 'L' t' and flow through theaforesaid longitudinal channels j j into a vessel placed below thestrainer. This mode of construction of the straining surface possessesthe advantage that the mounting,dis mounting and cleaning can be easilyand rapidly effected, there will be no totalization of the space whichmust be left between the strips, consequently the liquid will vbeclearer, the strips may be replaced by others for diminishing oraugmenting the size of the slits lt'according to the material to betreated; the strainer costs less than those heretofore employed and canbe easily kept in order, no special workmen being. required.

I claim as my invention- In a lter press,aseries ofstripslongitudinallygrooved .to form when placed side by sidelongitudinal channels with narrow slits at the front, in combinationwith segments to receive and retain the said strips and a casinginclosing the segments and strips to their full length, substantially asdescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
